a glass bottle completely filled with water is kept in the freezer why does it crack
Answers
Answer:
A glass bottle completely filled with water get cracked because water expands after freezing and if a completely water filled glass bottle is placed in freezer, the water would freeze and would expand resulting in the bottle to break.
Answer: When the volume of water (in form of ice) increases inside the glass it exerts a force on the walls of the glass, and when the force exceeds the maximum capacity of the glass it breaks.
Explanation:
A glass bottle completely filled with water and kept in a freezer will crack because:
→ The density of water is more than that of ice.
→ Also, we know that m = vρ
Where,
m = mass of the substance
v = volume of the substance
ρ = density of the substance
→ Because of this, the volume of ice is more than that of water.
→ Now, when the volume of water (in form of ice) increases inside the glass it exerts a force on the walls of the glass, and when the force exceeds the maximum capacity of the glass it breaks.
